How about a reading from a vacuum guage?? I've used one for years and it is an amazing diagnostic tool. Let us know... Cosmo
I agree. I already checked it. I am only pulling around 7" at idle, but it holds 15" like a rock at 1800 Rpm. The 7" is steady too. This should indicate that I don't have a valve sticking or anything like that, because valve train failures normally make the needle real jumpy at idle. Justice
